A Reconstruction of Northern Rio Grande Prehistory

Rio Grande Gummosis

Young Valencia orange trees were grown for three years in large outdoor sand cultures on complete nutrient solu tions that varied differentially only in the amount of boron. Three rates of boron were applied to single-tree plots. The plots were replicated four times. No difference in tree size resulted from the differential treatments. Rather large differences in the boron content of the leaves...

Mycobacterial ecology of the Rio Grande.

This is the first study to characterize the environmental conditions which contribute to the presence and proliferation of environmental mycobacteria in a major freshwater river. Over 20 different species of environmental mycobacteria were isolated, including the pathogenic M. avium and M. kansasii. Species of the rapidly growing M. fortuitum complex were the most commonly isolated mycobacteria...
